Why is New Brunswick’s fishing industry affected by seasonal changes and fish stocks?

New Brunswick’s fishing industry is inherently volatile, making it highly sensitive to both environmental and market-driven factors. The industry is significantly affected by seasonal changes and shifts in fish stocks due to the following reasons:

• Ecological Sensitivity: Fish populations are subject to natural fluctuations influenced by environmental conditions, such as water temperature and the availability of food sources like plankton. When these conditions change, they can impact the reproductive success and survival rates of various species.12
• Overfishing and Stock Depletion: The industry has historically faced challenges from overexploitation, where intensive fishing pressure—often enabled by advanced technology—has caused certain fish stocks to collapse or fall below levels necessary for natural replenishment.132
• Operational Volatility: Because the industry relies on these fluctuating biological resources, it is also susceptible to external pressures, including weather conditions, foreign competition, and credit availability.4

To mitigate these risks, the sector has become heavily dependent on government regulation, such as catch limits, quotas, and seasonal restrictions. Additionally, the province has increasingly turned to aquaculture to supplement traditional wild fisheries, providing a more controlled environment for producing species like salmon, trout, mussels, and oysters.43
